Abstract

PROBLEM TO BE SOLVED: To improve image pickup efficiency (diagnostic efficiency) by providing a means for rolling a subject between a first location easy to elevate and lower and a second location performing an X-ray photographing for a subject body on a top plate in a short direction, when the top plate is set to a standing position by a raising and laying means. SOLUTION: In an X-ray device, one end side of a supporting frame part 108 is fixed to a floor surface 109 and the other end side is fixed to a table part 107 via a raising and laying mechanism. After the raising and laying mechanism sets a top plate 101, the table part 107 and a subject 110 to a standing position by an image pickup termination instruction from an operator console, a rolling mechanism rolls the top plate 101 in a direction that the subject 110 gets on/off. Then, because an opening width formed by an X-axis (A' side) tip part of the top plate 101 and a restriction device 103 can be made L by rolling the top plate 101 in a direction shown by a solid line, that is, to the side where an instruction arm 111 is not arranged (right inclined position), the opening width for the subject 110 to get on/off can be widened to more than a conventional width.

TECHNICAL FIELD The present invention relates to an X-ray apparatus,
In particular, the present invention relates to a technique that is effective when applied to a top plate rolling device of an X-ray fluoroscopic table.

[0002]

2. Description of the Related Art A conventional X-ray apparatus is disclosed, for example, in
As described in -49852, a subject is set (mounted) on the inner surface side of a curved top plate, and a triangular guide portion (triangular guide plate) is provided on the outer surface side and near both ends, Two surfaces of each of the guides are supported by two rollers (rotating bodies) attached to the table. Each roller is connected via a gear mechanism to a motor for rolling the top plate in a direction perpendicular to the body axis of the subject, and by rotating the motor forward or backward, the X-rays for the subject are The center angle was rolled, and an X-ray image at a predetermined angle was captured. At this time, in the X-ray apparatus described in Japanese Patent Publication No. 55-49852, the shape of the guide plate, the diameter of each roller and the interval between the rollers are set to appropriate values, so that the center of the body axis of the subject is X-rayed. In addition to the setting on the center, a top plate and a rapid shooting device or an X-ray I.D. I. (Image intensifier) can be taken at a constant interval.

On the other hand, a conventional X-ray apparatus is manufactured on the premise that it is installed in a place where the installation space is relatively large, such as an apparatus installed in an X-ray room in a hospital or the like, and a gastric group. The distance between the X-ray source that irradiates the subject with X-rays and the top plate, in order to install it in a limited space, such as a device installed in an X-ray car used for medical examinations, and
Some devices have been manufactured by setting the distance between the top plate and the imaging system to a minimum necessary for capturing an X-ray image.

[0004]

SUMMARY OF THE INVENTION As a result of studying the above prior art, the present inventor has found the following problems.

[0005] In the conventional X-ray apparatus, the examiner is required to easily control the tilting angle and the rolling angle of the top plate during imaging while improving the efficiency of setting the subject on the top plate. , The tilting angle of the tabletop is controlled to be upright, and the vertical line at the center of the tabletop is controlled to be parallel to the tilting surface of the tabletop.

However, as described above, an X-ray device installed in a limited space such as an X-ray vehicle has a narrow space between the X-ray irradiator and the top plate, so that the end of the curved top plate is small. There is a problem that the distance between the part and the X-ray source is further reduced. For this reason, the conventional X-ray apparatus has a problem in that the time required for replacing the subject increases, and the diagnostic efficiency (imaging efficiency) decreases.

An object of the present invention is to provide an X-ray apparatus capable of making it easy for a subject to get on and off the X-ray apparatus.

Another object of the present invention is to provide an X-ray apparatus capable of improving imaging efficiency (diagnosis efficiency).

The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[0010]

When the top is set in the upright position, the subject is moved in the short direction between the first position where the subject can easily move up and down and the second position where the subject is X-rayed. Rolling means was provided.

(2) In the X-ray apparatus according to the above (1), the rolling means is means for rolling the top board upright and then rolling it to a laterally inclined position.

(3) In the X-ray apparatus according to the above (1) and (2), the top plate is provided with a triangular guide plate on the outer surface side, and two surfaces of the triangular guide plate are each a rotating body. Supported.

According to the above-mentioned means (1) to (3),
Based on the examination end instruction input by the examiner from the console or the like at the end of the X-ray photography, the elevating means sets the elevating angle of the tabletop to the standing position (0 degree) which is the angle for the subject to get on and off. ) Is set (raised), the rolling means rolls the top plate from the second position, which is the photographing position, to the first position (laterally inclined position), which is a position that is easy to ascend and descend. The person can easily go up and down on the top plate. Therefore, the time required for X-ray imaging can be reduced, and the diagnostic efficiency can be improved.

Further, even when the distance between the X-ray irradiation system including the X-ray tube and the diaphragm device and the top plate is narrow, it is possible to secure a space for ascending and descending to the top plate. X must be installed in a limited space such as an X-ray car
The best effect can be obtained when applied to a wire apparatus.

At this time, based on the examination end instruction at the end of the diagnosis, the tilting means first sets the top to the upright position (falls), and then the rolling means moves the top from the second position to the first position. In addition, there is an effect that the top plate can be set at the elevating position while the posture of the subject is stabilized by rolling the subject to the position.
